Recently, various types of electronic devices, such as a mobile phone, a tablet personal computer (tablet PC), an MP3 player, a portable multimedia player (PMP), an e-book, and the like, have been provided so that a user can access various contents through such electronic devices. In addition to wireless transmission and reception functions, various functions such as multimedia functions such as picture, music, and video playback, entertainment functions such as games, and the like are concentrated in the electronic device. As the mobile communication service extends to the multimedia service area, a user can use multimedia services as well as voice calls and short messages through electronic devices.

The electronic device is made thin and light for portable purposes. Since the electronic device may be damaged due to an external physical shock, the electronic device may be used together with an exterior cover (or case) surrounding the exterior of the electronic device. The exterior cover surrounding the exterior of the electronic device may not only provide a function of protecting the electronic device but also may exert an aesthetic effect on a user.

Meanwhile, the electronic device is provided with a camera on the front, rear, or both surfaces thereof so that a user can take a picture of a desired object. Here, when the user takes a picture of himself or herself using the camera provided in the electronic device, the user may not be able to take a picture at a desired angle and distance due to a limitation of the body length (e.g., the length of the arm of the user). In order to solve this problem, according to some embodiments, a user may take a picture using a “tripod” or using a tool called a “selfie stick” which is popular in recent years.

However, a tool such as a tripod or a selfie stick is bulky, so it is practically difficult for the user to carry it at all times. Even if the tripod or selfie stick is carried at the time of taking a picture, there is a problem that a time-consuming and cumbersome preliminary process is required in coupling and operatively connecting the tripod or the selfie stick to the electronic device.

According to an embodiment, the electronic device mounted on the cover portion 100 may include all electronic devices that are generally small so as to be portable by a user and in which a camera may be disposed on the front, rear, or both surfaces thereof.

The cover portion 100 may include a first plate 110 that is provided with a front surface 111 facing a first direction (e.g., a direction “{circle around (1)}” described later in FIG. 9) and a rear surface (e.g., 112 of FIG. 3 described later) facing a direction (a direction “{circle around (2)}” described later in FIG. 9) opposite the first direction, and may further include a side member (e.g., side surface) 120 extending from an edge of the first plate 110. For reference, in relation to direction components illustrated in FIGS. 1 and 2, and the following drawings, direction components X, Y, and Z may refer to a reference direction corresponding to a rectangular coordinate system in space. According to various embodiments, the first direction (e.g., the direction “{circle around (1)}” described later in FIG. 9) may be a direction parallel to a direction in which the direction component Z faces, and the second direction (e.g., the direction “{circle around (2)}” described later in FIG. 9) may be a direction parallel to a direction opposite the direction in which the direction component Z faces. According to various embodiments, the side surface of the cover portion 100 may face a direction perpendicular to the front surface 111 and the rear surface 112, respectively. For example, a direction in which the side surface faces may include a direction parallel to an X-axis or a Y-axis in the direction components.

The side member 120 of the cover portion 100 may be provided to surround at least a portion of the electronic device. The side member 120 may extend in a direction substantially perpendicular to the edge of the plate 110. In this case, the side member 120 may have a partially curved shape while facing in a substantially vertical direction from the plate 110.

Referring to FIG. 2, when the cover portion 100 is viewed from the front, the opening 114 may be provided at a lower end of the side member 120. According to various embodiments, the opening 114 may be provided to correspond to an ear jack insertion hole, a USB terminal insertion hole, or the like provided in a housing of the electronic device. The opening 114 may be deformable according to the electronic device mounted on the cover portion 100, and thus may be placed at a position different from that shown in the drawing. According to various embodiments, a plurality of openings 114 may be provided in the side member 120. As an example, as shown in FIG. 2, two openings 114 may be provided in the side member 120. The two openings 114 may be provided at one side and the other side of the side member 120, respectively. As shown in FIG. 2, when the cover portion 100 is viewed from the front, the opening 114 may be formed at an upper end and a lower end of the side member 120, but is not limited thereto, and other various embodiments related to the size, shape, or position of the opening 114 may be applicable.

According to an embodiment, a surface that the side member 120 faces may be referred to as the side surface of the cover portion 100, but is not necessarily limited thereto. For example, as illustrated in FIGS. 1 and 2, the outermost portion (e.g., the end of the first plate 110) of the cover portion 100 in which the opening 114 is provided may also form the side surface. For example, in a vertical mounting mode of the electronic device, when the side surface of the cover portion 100 contacts the support portion, a portion contacting the support portion may correspond to the side surface of the support portion.

According to various embodiments, another opening 115 may be additionally provided in the cover portion 100. The opening 115 may be provided at a position corresponding to a rear camera of the electronic device.

Referring to FIGS. 3 and 4, the exterior cover 10 according to various embodiments may further include a support portion (e.g., a support) 200 for mounting the cover portion (e.g., cover) 100 at various angles with respect to the ground while stably supporting the cover portion 100.

The support portion 200 may be connected to the rear surface 112 of the cover portion 100, and the shape of the support portion 200 may vary according to any one of a plurality of mounting modes for the electronic device to maintain a designated angle with respect to the ground.

The ground does not refer only the surface of the earth or the ground, but may refer to a reference surface according to various embodiments on which an electronic device or the exterior cover 10 may be placed. For example, the ground may refer to various surfaces, such as, for example, and without limitation, a rock, a work table, a dining table, an automobile center fascia, or the like, in addition to the ground surface and the ground. In addition, the ground does not necessarily refer only the ground parallel to the horizontal plane, and may also include all inclined, irregular, and uneven ground.

The support portion 200 may support the cover portion 100 in accordance with the plurality of mounting modes for the electronic device to maintain a designated angle with respect to the ground.

The plurality of mounting modes may include, for example, a rear camera photographing mode where a direction in which the rear camera of an electronic device (e.g., a mobile terminal) faces is perpendicular to the ground or forms an obtuse angle with the ground while the electronic device is coupled to the exterior cover 10, and a front camera photographing mode where a direction in which the front camera of the electronic device faces is perpendicular to the ground or faces an obtuse angle with the ground. The rear camera photographing mode may refer, for example, to an inclined angle being maintained while the rear camera of the electronic device faces a direction horizontal to the ground or faces more upward than the direction horizontal to the ground. The front camera photographing mode may refer, for example, to an inclined angle being maintained while the front camera of the electronic device faces a direction horizontal to the ground or faces more upward than the direction horizontal to the ground. When the rear camera is perpendicular to the ground or the front camera is perpendicular to the ground, one of, for example, the rear camera photographing mode and the front camera photographing mode may be selected.

According to various embodiments, the rear camera photographing mode and the front camera photographing mode may further include a horizontal photographing mode and a vertical photographing mode, respectively. For example, the rear camera photographing mode may be divided into a rear camera horizontal photographing mode and a rear camera vertical photographing mode. This will be described in detail with reference to the following drawings.

According to an embodiment, in the rear camera photographing mode and the front camera photographing mode, the rear surface 112 of the cover portion 100 may be in contact with a first contact point of the support portion 200, and a portion of the electronic device or a portion of the side surface of the cover portion 100 may be mounted while being in contact with a second contact point of the support portion 200 (see FIG. 5 described later).

In any one of the plurality of mounting modes, the electronic device and/or the exterior cover 10 may maintain an angle designated in the corresponding mounting mode.

According to various embodiments, in the plurality of mounting modes, the cover portion 100 may be provided to be in contact with the support portion 200 in at least two different portions thereof. For example, in the rear camera photographing mode as well as the front camera photographing mode, the cover portion 100 may be in contact with the support portion 200 in at least two different portions thereof, thereby stably maintaining a designated angle.

The support portion 200 may generally have a shape extending in the longitudinal direction (e.g., a direction parallel to an X-axis) of the exterior cover in another area other than an area in which the opening 115 is provided, on the rear surface 112 of the cover portion 100.

According to various embodiments, a groove 113 for allowing the support portion 200 to be seated thereon may be provided in the rear surface 112 of the cover portion. One surface (a surface facing in a direction parallel to the Z-axis direction of FIG. 3 when the support portion is folded into a plate shape) of the entire support portion 200 may be provided to face the groove 113 while the support portion 200 is in a folded state. According to an embodiment, the support portion 200 may have a shape that fits into the groove 113.

When the support portion 200 is folded, the support portion 200 may have a flat plate shape such as the first plate 110 of the cover portion 100. Hereinafter, when the support portion 200 has a plate shape, the support portion 200 may be referred to as a “second plate” to clearly distinguish from the first plate 110.

Referring to FIGS. 3 and 4, the support portion 200 may include a first support portion 210 configured to be in contact with the floor in the plurality of mounting modes; a second support portion 220 configured to be rotatably coupled to the first support portion 210; and a third support portion 230 configured to be rotatably coupled to the second support portion 220 and to be fixedly provided on the rear surface 112 of the cover portion 100.

The first support portion 210 may be configured to be in contact with the ground in the support portion 200 in the plurality of mounting modes, and when the first support portion 210 has a plate shape, the first support portion 210 may be configured to surround the second support portion 220 and the third support portion 230. In the foregoing description of the rear camera photographing mode and the front camera photographing mode, the above-described second contact point which may, for example, be a portion where the side surface of the electronic device or the cover portion 100 is in contact with the support portion 200 may correspond to any one portion of the first support portion 210.

The third support portion 230 may be configured to be fixed to the rear surface 112 (or the groove 113) of the cover portion 100. In the foregoing description of the rear camera photographing mode and the front camera photographing mode, the above-described first contact point which may, for example, be a portion where the rear surface 112 of the cover portion 100 is in contact with the support portion 200 may be provided through the third support portion 230.

The second support portion 220 may be connected at one side thereof to the first support portion 210 and connected at the other side thereof to the third support portion 230. In relation to the cover portion 100, the first support portion 210 may correspond to an intermediate member provided between the third support portion 230 forming the first contact point and the first support portion 210 forming the second contact point.

According to various embodiments, the second support portion 200 may be configured to include three rotational axes to give various and free angle changes to the electronic device or the cover portion 100. According to an embodiment, the three rotational axes may include a first rotational axis (e.g., a first rotational axis A1 of FIG. 5 to be described later), a second rotational axis (e.g., a second rotational axis A2 of FIG. 5 to be described later), and a third rotational axis (e.g., a third rotational axis A3 of FIG. 8 to be described later). In addition, according to an embodiment, the second support portion 220 may be rotatably coupled to the first support portion 210 in a first rotational axis direction, and the third support portion 230 may be rotationally coupled to the second support portion 220 in a second rotational axis direction. In addition, the third support portion 230 may be configured to allow the first support portion 210 and the second support portion 220 to be rotatable in a third rotational axis direction perpendicular to the first rotational axis direction and the second rotational axis direction, in addition to the second rotational axis direction.

FIG. 5 is a perspective view illustrating an example operation of unfolding the support portion 200 of the exterior cover 10 according to various embodiments. In FIG. 5, a state in which the shape of the support portion 200 of the exterior cover 10 varies is illustrated.

As to the support portion 200 that is separated from the groove 113 of the cover portion 100, the first support portion 210 may rotate independently of the second support portion 220, the second support portion 220 may rotate independently of the third support portion 230, or the third support portion 230 may rotate independently of the first support portion 210 and the second support portion 220.

The first support portion 210 may rotate by a predetermined angle along the direction of the first rotational axis A1 with respect to the second support portion 220, and the second support portion 220 may rotate by a predetermined angle along the direction of the second rotational axis A2 with respect to the third support portion 230.

Referring to FIG. 5, as sequentially illustrated in FIG. 5, the second support portion 220 may be separated from the groove 113 while the first support portion 210 is separated from the groove 113, and the second support portion 220 may be separated from an opening O provided in the first support portion 210. The first support portion 210 may be inclined at a predetermined angle with respect to the second support portion 220 by rotating along the direction of the first rotational axis A1 with respect to the second support portion 220. The second support portion 220 may rotate along the direction of the second rotational axis A2 with respect to the third support portion 230 whose position is fixed. In this state, when the second support portion 220 further rotates along the direction of the second rotational axis A2, the first support portion 210 may approach a side of the lower end of the exterior cover 10. When the second support portion 220 further rotates, the first support portion 210 may face at least a portion of the front surface of the cover portion by passing by the lower end of the exterior cover 10. Through this operation, the first support portion 210 may be positioned below the lower end of the exterior cover 10, and one surface of the first support portion 210 may support a portion of the exterior cover 10 (or a portion of the electronic device) from below.

As illustrated in FIG. 5, according to various embodiments, by simply rotating the first support portion 210 and the second support portion 220 along the directions of the two rotational axes A1 and A2, respectively, a stable mounting mode can be provided. According to various embodiments, as illustrated in FIG. 5, the exterior cover 10 has an advantage of easily implementing a mounting operation in the rear camera photographing mode.

Hereinafter, according to various embodiments, the support portion 200 will be described in more detail.

FIG. 6 is a diagram illustrating the support portion 200 according to various embodiments. FIG. 7 is a cross sectional view of the support portion 200 illustrated in FIG. 6 taken along index line B-B′ and index line C-C′. Referring to FIG. 6, a front view of the support portion 200 and a side view of the support portion 200 viewed from four different sides are illustrated.

Referring to FIG. 6, the support portion 200 may include at least three components, for example, the first support portion 210, the second support portion 220, and the third support portion 230. According to various embodiments, the support portion 220 may further include additional components (e.g., when the first support portion 210 is divided into a 1-1 support portion and a 1-2 support portion as at least two different link members), but description will be made below based on the three components.

According to various embodiments, the first support portion 210 may include an opening O described with reference to FIG. 5; a frame 211 configured to surround the opening; and a planar portion 212 to be configured to be at least partially surrounded by the frame 211.

The frame 211 may be provided to surround the opening O and the planar portion 212, and the second support portion 220 and the third support portion 230. Thus, a width L1 of the frame 211 may be larger than the widths of the second support portion 220 and the third support portion 230. A length L2 of the frame 211 may also be larger than the lengths of the second support portion 220 and the third support portion 230.

The planar portion 212 may be provided such that at least a portion of the planar portion 212 faces the third support portion 230 in a folded state (or “non-mounting mode”) of the support portion 200, as illustrated in FIG. 6. According to an embodiment, the at least one portion thereof may have a shape corresponding to the outer shape of the third support portion 230. For example, when the third support portion 230 has a substantially circular shape as illustrated in FIG. 5, at least a portion of the planar portion 212 may form an arc.

As illustrated in FIG. 6, at least a portion of the second support portion 220 may also be provided to face the third support portion 230 in a folded state (or “non-mounting mode”) of the support portion. According to an embodiment, the at least a portion of the second support portion 220 may have a shape corresponding to the outer shape of the third support portion 230. For example, when the third support portion 230 has a substantially circular shape when viewed from above as shown in FIG. 5, the at least a portion of the second support portion 220 may form an arc.

According to an embodiment, the third support portion 230 may have a circular shape when viewed from above the rear surface 112 of the cover portion 100, but is not necessarily limited thereto. The third support portion 230 may have a variety of shapes such as, for example, and without limitation, a triangle, a rectangle, five or more polygons, etc., and the shapes of the planar portion 212 and the second support portion 220 may also be changed to shapes corresponding thereto.

According to various embodiments, the second support portion 220 may have at least one fastening structure to prevent and/or reduce from being separated from the third support portion 230 while the above-described rotation operations (e.g., rotation in the second rotational axis direction and rotation in the third rotational axis direction) are performed. For example, as shown in the cross sections (e.g., the cross-section in a direction of index line C-C′) of the second support portion 220 and the third support portion 230 of FIG. 7, a protrusion 221 protruding from the second support portion 220 toward the third support portion 230 may be fastened to a groove 231 provided in the third support portion 230. In addition, a fastening structure according to various embodiments is applicable.

According to an embodiment, the planar portion 212 may form a flat plate shape with the second support portion 220 and the third support portion 230. Referring to FIGS. 6 and 7 together, in the folded state (or “non-mounting mode”) of the support portion 200, the planar portion 212, the third support portion 230, and the second support portion 220 may be sequentially arranged from one side of the support portion 200 and may be coupled to each other to form one flat plate. In addition, according to an embodiment, the planar portion 212, the second support portion 220, and the third support portion 230 may be provided to have substantially the same thickness. For example, as shown in FIGS. 6 and 7, as the first support portion 210 has a thickness L3, each of the planar portion 212, the second support portion 220, and the third support portion 230 may have the thickness L3 or a thickness thinner than the thickness L3 to form one flat plate.

The conventional exterior cover discloses only the configuration of a simple cover portion for providing protected usage or various colors or textures. However, according to the disclosure, the support portion 200 may have the same structure as the above-descried embodiment to form a smooth appearance, thereby providing an effective user convenience function without compromising the aesthetics.

Referring to FIG. 10, in the rear camera photographing mode of the electronic device, a portion (or a portion of the electronic device) of the side surface of the exterior cover 10 may be in contact with the second surface 215 of the first support portion 210 thereon.

In the vertical photographing mode of the embodiment shown in FIG. 8, a user may simply rotate the cover portion 100 along the third rotational axis A3 by a predetermined angle (e.g., 90 degrees), and thus the same photographing mode as the embodiment shown in FIG. 10 may be implemented.

Referring to FIGS. 11A, 11B, and 11C, various examples of the horizontal photographing mode are shown. Various angles α1′, α2′, and α3′ formed by the first support portion 210 and the second support portion 220 may be an acute angle. Angles β1′, β2′, and β3′ formed by the first support portion 210 and the cover portion 100 may be changed depending on angles α1′, α2′, and α3′ formed by the first support portion 210 and the second support portion 220.

FIG. 11A illustrates a general rear camera horizontal photographing mode in which each of angle α1′ formed by the first support portion 210 and the second support portion 220 and angle β1′ formed by the first support portion 210 and the cover portion 100 is an acute angle.

FIG. 11B illustrates a rear camera vertical photographing mode that is approximately perpendicular to the ground, wherein angle α2′ formed by the first support portion 210 and the second support portion 220 is an acute angle, and angle β2′ formed by the support portion 210 and the cover portion 100 is substantially perpendicular. In this case, the user may select the front camera horizontal photographing mode instead of the rear camera horizontal photographing mode.

FIG. 11C illustrates a front camera horizontal photographing mode in which angle α3′ formed by the first support portion 210 and the second support portion 220 is an acute angle, but angle β3′ formed by the support portion 210 and the cover portion 100 is an obtuse angle.

Referring to FIGS. 11A, 11B, and 11C, a user may simply adjust angle α′ formed by the first support portion 210 and the second support portion 220 to change angle β′ formed by the first support portion 210 and the cover portion 100, whereby the mounting mode of the electronic device can be implemented more variously and freely. The user may finely adjust an inclination angle of the electronic device with respect to the ground, and if it is determined that a predetermined angle is suitable for taking a picture, the user may perform a photographing operation while stably maintaining the corresponding angle.

Based on a comparison between the embodiments of FIGS. 9A, 9B, and 9C and FIGS. 11A, 11B, and 11C, in the horizontal photographing mode of FIGS. 11A, 11B, and 11C, the side surface of the cover portion 100 may contact the second surface 215 and a portion contacting the ground may not be provided.

According to various embodiments, in the rear camera photographing mode and the front camera photographing mode, a portion of the first support portion 210 in contact with at least a portion of the electronic device or the exterior cover 10 (e.g., at least a portion of the second surface 215) may include an anti-slip portion (e.g., a portion containing a frictional material). For example, the at least a portion of the second surface 215 may be made of a material having high frictional force such as rubber and urethane. As a result, when the electronic device or the external cover is mounted on the first support portion 210, it is possible to prevent the electronic device or the external cover from sliding on the second surface 215 unless the user forcibly applies an external force.

Referring to FIGS. 5 and 8 and FIGS. 11A, 11B, and 11C together, according to various embodiments, the first support portion 210 may rotate with respect to the second support portion 220 by a first maximum allowable angle along the direction of the first rotational axis A1. According to various embodiments, the second support portion 220 may rotate with respect to the third support portion 230 by a second maximum allowable angle greater than the first maximum allowable angle along the direction of the second rotational axis A2. Here, the first maximum allowable angle may be a maximum allowable angle of angle α formed by the first support portion 210 and the second support portion 220, and may correspond to, for example, 60 degrees or 90 degrees. The second maximum allowable angle may be a maximum allowable angle of an angle formed by the second support portion 220 with respect to the third support portion 220, and may correspond to, for example, 180 degrees. On the other hand, since the third support portion 230 rotates in place in a state of being fixed to the rear surface 112 of the cover portion 100 and does not have a structure preventing rotation around the third support portion 230, thereby allowing the first support portion 210 and the second support portion 220 to rotate (rotate 360 degrees) along the direction of the third rotation axis A3 without angle limitation.

Here, the first magnetic material 216 and the second magnetic material 220 may be configured to form mutual attraction. By an attraction force acting between the first magnetic material 216 and the second magnetic material 220, a user may restore the support portion 200 in a folded state with little force. Embodiments of the first magnetic material 216 and the second magnetic material 220 shown in FIGS. 14A and 14B are merely examples. In addition, various numbers of magnetic materials may be provided and used at various positions.

According to various embodiments, the exterior cover 10 may include one or more nail grooves 213 and 213′.
